To understand the rewind mechanic is not an easy task as your character go back to the original point when you rewind. But when you understood it, it's really cool and the levels are cool too. For the last part (with two doors), I know I have to use my brain... wasn't easy... But I finished it !
The game aesthetic is clean and the gameplay too.
As you said, it's important to use a controller, with keyboard it's not fun.
Great job !
